FENCE-BUILDING MACHiNE.

QPECIFICATION forming part of Letters Patent No. 331,320, dated December 1, 1885.

Application filed August 7, 1885. Serial No. 173,883. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM N. PARRISH, a citizen of the United States, residing at Richmond, in the county of WVayne and State of Indiana, have invented certain new and useful Improvements in Fence Building Machines, of which the following is a specifica tion, reference being had therein to the accompanying drawings.

My invention relates to that class of movable machines used in the construction of combined wire and picket fences.

My invention consists in certain new combinations and arrangements of devices for twisting the wire between the pickets of the fence, as will be more fully hereinafter described, and specifically pointed out in the claims.

In the drawings, Figure 1 is a side elevation. Fig. 2 is an end elevation. Fig. 3 is a top View. Fig. 4is an enlarged detail view showing the standard and supporting-arm of one of the twisting-wheels. Fig. 5 is an enlarged detail view of the twisting-wheel.

In Fig. 1, A represents an open-linked belt passing over the driving-wheel and each of the twisting-wheels.

B is a vertical standard to which the arms 0 are secured in a horizontal position, serving to support at their outer ends the twistingwheels 5 b b. I

or represents the drivingwheel, having its bearing upon the arm 0, which is secured to the top of the standard 0. To a is attached a crank, m, having a handle, n. The wheel is provided with projections eon its periphery, which fit in the openings of the chain belt, said chain belt A passing over and fitting upon similar projections e of the twisting-wheel b,

and thereby giving motion to said wheel when l the driving-wheel a is operated by means of the crank-arm m.

d is an angular brace secured to the standard B and joined to the arm 0 for the purpose of supporting the bearing of the drivingwheel. 7 I

The twisting-wheel b is of circular form, flattened or straight in the sections of its circumference, and provided with projections 6. It is made, preferably, of cast-iron in skeleton form, having openings 0 0 between its center and outer edge,

0 is an opening in the circumference communcating with one of the openings 0, and terminating in a circular recess, 2', to receive and hold the wire to be used. These openingscc are on opposite sides of the circumference of the wheel b, and are of similar construction, adapted to carry two wires used in the construction of the fence.

The central portion of the wheel 0 is composed of an annular projection, h,which forms the hub or journal of the wheel, having its bearings in the jointed circular frame I) b, forming the outer end of the horizontal support 0. This bearing b b is jointed at Z, Fig. 4, and is adapted to be opened or closed, as shown by dotted lines in Fig. 4. When closed, the inner surfaces form a close'fitting bearing,- in which the twisting-wheel b is permitted to revolve freely as operated by the opened-link belt A. The wires to be twisted are passed through the openings 0 0 into the recesses 13 6 previous to the wheel I) being placed within its bearings b I), and the recesses it are made sufficiently large to allow the splice of the wire to pass through the same.

The supporting-arms G O O are made adjustable vertically upon the standard B by means of slots 01 d 01, through which screw-bolts pass, having nuts t to hold them in their required position.

The letter p indicates a recess in which the free end of the frame b is adapted to rest and be secured by a suitable pin.

The operation of my machine is as follows: The standard B is suitably supported in :a vertical position in any convenient manner. The wires to be used are firmly secured to an initial post at proper distances asunder, the ends being placed in the recesses i t of each wheel I), the opposite and distant end of the wire being attached to any suitable device for holding or stretching the same, the wires of the upper and lower rollers being run in within the belt and slipped into the recesses through the openings 0, the wire of the intermediate wheel being passed in in front of the belt. The driving-wheel ais then turned by means of the crank at until each twisting-wheel is given as many revolutions as are wanted to make the first twist in the wires against the initial post. A picket is then placed within the forks 0f the wires and held there, while the driving wheel is turned in an opposite direction from the first, giving the twisting-wheelsa reverse motion and gripping the picket between the first and second twists of the wires, the latter being in an opposite direction from the first, thereby relieving the main wires on that side of the machine oppositethe picket from the twist given it by the first operation. An equal number of revolutions of the twisting-Wheels Z) Z) Z) in each direction makes the twist of the wire between the pickets uniform and alternately right and left, and the machine is allowed to slide along the wires, receding from the pickets as they are fixed in place and the fence is formed.

A greater or less number of twistingwheels may be arranged on the standard B, in accordance with the number of strands of wire desired to be used in the construction of the fence.

What I claim is 1. The standard B, having slots d d d, arms 0 G C, and clamping-bolts, the arms being provided with a jointed circular bearing-frame, b b, and the wheels I) b b, in combination with the wheel a and belt A, as and for the purposes set forth.

2. The twisting-wheel I), provided with openings c c and recesses i i, and arranged to revolve within the pivoted bearing-frame b b, substantially as specified.

In testimony whereof Iaffix my signature in presence of two witnesses.
